• examples of good concurrent programs meant to scale

  - by vishr

  I am looking for seminal and excellent examples of libraries and projects that emulate the good practices of the Java Concurrency in Practice book. The book is marvelous. However, I think supplementing this book reading with code reviews of projects and libraries that make use of the concurrency APIs effectively is necessary to drive the concepts into the brain. One good example of what I am looking for is https://code.google.com/p/concurrentlinkedhashmap/ Can folks help me with finding exemplary, well written code that use the concurrency api well?

• Generic DRM (Distributed resource management) wrapper

  - by Pavel Bernshtam

  I need to write a software, which launches DRM jobs in a customer environment and monitors those jobs status. It should work with various customer environments and DRMs - like LSF, Sun Grid and others. Can you recommend some 3rd party library, which hides DRM differences from me and has API like "launch job", "get list of jobs", "get job status" etc. ? Both Java and native libraries are good for me.

• Can someone explain what does <? super T> mean and when should it be used and how this construction

  - by Roman

  I'm using generics rather long time but I've never used construction like List<? super T>. What does it mean? How to use it? How does it look after erasure? I also wonder: is it something standard in generic programming (template programming?) or it's just a java 'invention'? Does c#, for example, allow similar constructions?
